Answer:
HNO₃.
Explanation:
- It is known that acids decrease the pH of the solution, while bases increase the pH of the solution.
So, HF and HNO₃ decrease the pH of the solution as they produce H⁺ in the solution.
<em>While, KOH and NH₃ increase the pH of the solution as they produce OH⁻ in the solution.</em>
<em />
HNO₃ will decrease the pH of the solution greater than HF.
- Because HNO₃ is strong acid that decomposes completely to produce H⁺ more than the same concentration of HF that is a weak acid which does not decomposed completely to produce H⁺.
Answer:
No
Explanation:
The conclusions from Thomoson's claims would be invalid if his experiment could not be replicated.
<em>One of the attributes of a valid experiment in science is replication. That is, an experiment must be repeatable with similar outcomes under similar conditions as the original experiment when independently performed by another scientist. Once an experiment cannot be replicated, the outcomes of such an experiment become invalid in science.</em>
Hence, <u>Thomoson's conclusion would be invalid if his experiment could not be replicated. </u>
The volume of the gas when the pressure of the gas increases to 755mm hg is calculated as follows
by use of boyles law formula that P1v1=P2V2
V2= P1V1/P2
V1=5.58 L
P1= 715 mm hg
P2=755 mm hg
V2 is therefore= ( 715 mm hg x 5.58 L) /755 mm hg= 5.28 L
When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the color of the object in that light. For example, a blue object absorbs all the colors of the spectrum except blue, it reflects blue light. hope this can help.
